Companies don't do anything unless it's either to satisfy a regulatory requirement or to "manufacture profits", full stop. For traditional IT departments the profit part is a bit indirect compared to Facebook (IT theoretically improves employee productivity and thereby enables higher profits - cue laugh track here), but the profit motive is there all the same. This comparison is a bit specious.

The thing that's really different is the nature of the workload. Facebook is almost a poster child for the sort of highly parallel/low-integrity workloads that microservers handle best (though they've been cutting it a bit close on the "low-integrity" part of late).

Does Google make their own chipsets? Their own DRAM parts? Their own flash? Their own disk drives?

The only thing they've really taken on is PCA design/fabrication and system assembly. Those are pretty darned easy, as evidenced by the sheer number of Taiwanese/Chinese ODMs that do both. Google are a long, long way from doing their own CPUs. They clearly could if they wanted (they have the reputation to attract top talent and money to pay for it) but they're a long way from there right now. If they do decide to go there you'll see it coming from a mile away, when they try to buy a top-notch design team like Apple did with PA Semi.
